March is a low season, with around 20% of the island is crowded. Although there are more tourists visiting at this time than during other months, many restaurants and hotels will be closed or just reopening for business. Beaches may still be relatively empty, but it won’t appear like a ghost town either. By April, that number jumps to 40% as high season begins to approach and Greek Easter brings in additional visitors on top of those planning their summer vacations – practically all businesses open up by then.

 May is the perfect time to visit this idyllic island; it’s bustling without feeling overcrowded. The beaches are brimming with activity, and there’s no shortage of businesses offering their services. After all, who can resist weather that feels like a tropical paradise?

As it’s peak season, anticipate crowds and have your bikini/swim trunks ready for some beach or pool time. It may be busier than August, but you’ll still have an incredible experience with hot weather all around.

 August is highly overcrowded, as it’s the busiest month for Santorini – if you can avoid this period since everything takes more time and effort. Come to September and experience the hustle of High season! The crowds may feel like an extension of August, but it will start to thin out by the end. Enjoy summery weather while you can – check below for more information on what this month has in store. 

October is a bustling time of year, with 70% occupancy rates and cooler weather that still permits swimming in the sea or pool.

December brings a light crowd of just 10% during the heart of the Low season.

August brings intense heat along with gusty winds that are perfect for water sports.

Autumn

As September begins, the summer warmth still lingers in the air, and beautiful sunlit days are plentiful. Yet slowly, cool nights start to arrive with stunning colorful skies that accompany them. This serene atmosphere makes it perfect for a peaceful swim or any other outdoor activity on this magnificent island – all while being far less crowded than usual!

As the summer months come to a close, September in Santorini brings with it beautiful weather – hot and sunny but slightly cooler than June. It is at this time that the water warms up after heating through the warmer days of summer. October seems much like May weather – still warm but with signs of winter’s chill beginning to show its face as we approach November. In November, what begins as cloudy skies culminates into cool winter days becoming more frequent until December arrives, fully embracing frosty mornings and evenings alike.

Winter

If you plan to explore Santorini in December, prepare for the chilly and wet weather with occasional strong winds. Despite this, it is an ideal time to experience a more genuine side of the island – most tourist hotspots are closed, leaving only friendly small taverns and quaint shops open for exploration. Additionally, take advantage of clear days to admire breathtaking views or embark on leisurely hikes!

From January to February, the chill of Santorini is unmistakable. Although the island remains void of tourists in both months, January usually experiences more rain and colder temperatures than February. Some locals even say that February is typically the coldest month in this picturesque location!

Must-have items for Santorini

When planning a trip to Santorini, it’s important to consider the season and month. During winter (December-February), you’ll want jackets, long sleeves, sweaters, and jumpers; however, shorts or summer dresses are not recommended due to the windy and humid temperatures that can still be quite cold. It is worth noting that January & February tend to be the chilliest months in both Greece and Santorini, with potentially erratic weather conditions – but no extremes!

Winter in Santorini is like the fall/autumn season of prominent European cities such as Paris and London; you never know what to expect, with temperatures ranging from 3°C with drizzle all the way up to 20°C and sunshine. It’s true that there can be a few days where it snows on the island – however, for those accustomed to extreme snowfall, this may seem more like a joke!

In May, say goodbye to winter wear and pack your swimsuits! Santorini’s March climate can be unpredictable, yet nothing that should give you cause for concern. You will likely have days of 15-20 degrees Celsius accompanied by sunrays – a welcomed respite from the cold! Springtime in April normally brings with it balmy temperatures around 25°C along with bright blue skies; however, if you’re looking to take a dip in the sea, then look no further than May. Although still slightly chilly from its hibernation during the Winter months, this is definitely the month for swimming adventures in Greece’s renowned Santorini.

If you are visiting the sunny island of Santorini in May, it’s best to pack your swimsuits and summer clothing, such as bikinis, monokinis, shorts, t-shirts, and dresses. In contrast, if April is your month of choice for a getaway, then be sure to bring jackets and other warm clothing items. It feels like summertime in major cities across Europe during May in Santorini!

Summertime is the perfect season for soaking in the sun and enjoying breathtaking views. From bikinis to monokinis, swimsuits to speedos, and flip-flops to summer dresses, it’s time to have some fun! The weather in Santorini is just right- not too hot (like a desert) but still warm enough that you can wear shorts and skirts year-round. Dare we say it? It might be the best summer ever with temperatures like these!

As we move into the Fall/Autumn months of September, October, and November, days may still feel like summer. However, you should bring a light jacket for those chilly nights. During this time period, most activities will take place on beaches or swimming pools where temperatures are usually warmer than average! By the time October arrives, it is likely to be your last chance to enjoy some fun in the sun without feeling too cold. So make sure you get outside as much as possible while these autumnal conditions permit! 

As the temperature begins to drop in November, swimming may become more difficult to enjoy. You should plan on wearing long sleeves for most days of that month; however, you can also anticipate some spectacularly sunny and warm days with temperatures reaching 20 degrees Celsius! What a treat!
